That doesn’t solve anything; you still have to write the nested function, which means you still need to know what the order is. That’s only going to come through the documentation or non-compiler verified labels. It also doesn’t help the call site for `doResize` - you’ll still get the non-descript `(Image, Image)` values. -David _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
